GUSTAVE CARLSON, OF CHICAGO, ILLINOIS.

DRAIN-CONNECTOR.

Specification of Letters Patent.

Patented an. 8,1918.

Application filed October 4, 1917. Serial No. 194,642.

To all whom it may concern:

Be 1t 'known that I, GUSTAVE CARLSON, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Drain-Connectors, of which the following is a specification.

This invention relates -to drain connectors, and particularly to drain connectors which are applied to roofs of buildings and which are attached to the down spout of the building which carries off the water from' the roof. i

The object of the invention is to provide an improved form of connector so arranged as to be applied more conveniently than ordinarily; so that the strainer of the connector may be more conveniently removed and replaced; and so as to eliminate" any leakage around the connector, especially through the bolt holes which connect the strainer with the bowl of the connector.

In the accompanying drawings Figure 1 is a plan view of the strainer and the con-' nector; Fig. 2 is a central vertical section along the line 2-2 of Fig. 1, which shows the features of my invention.

The drain conneetorcomprises a bowl 5 having at its lower end means for connecting, in any suitable manner,'to the down spout 6, such as the ordinary form of pipe threads. The bowl may be made of any suitable shape, but it has at its upper edge an annular flange 7 extending'inwardly from the walls of the bowl. Over the bowl a strainer 8 is placed which may be made in any suitable manner and of any suitable material; for example the strainermay be made of cast iron and bell shaped as indie cated by the drawing, with slots 9-' through which the roof water is free to passinwardly through the bowl and down the spout; the aggregate of the openings 9 being much larger than the cross section of-the down spout 6, so as to avoid undue accumulation of water on the roof. The lower edge of the strainer has an annular flange 10 extending outwardly therefrom, and substantially corresponding in dimensions to the flange 7; and bolts llare used't-oclamp the two flanges together. It is 'to be understood, however, that the strainer may be connected to the flange 7 of the bowlin any suitable nector is placed in the manner.

As is well'understoodi the down spout cono'west portion of the roof, so. as to receive the water falling on the roof. The bowl 5 is fixed in the roof 12 in any suitable manner, and when desired flashing 13 is placed on the roof extending between the flanges? and 10 of the bowl and strainer, as indicated in Fig. 2; the flashing having an opening 14: therethrough which allows strainer to pass freely into the bowl. Over the flashing gravel 15, or other suitable material, is placed when desired.

A consideration of the drawings and the following description will show that, by this arrangement, as the lower ends of the bolts 11 pass within the bowl, ample room is provided for the bolts to project below the the water passing through 'the' flange 7. It is common in practice for the bowls to be surrounded by cement so as to hold them firmly in place and for the flange at the upper end of the bowl to extend externally instead of internally. In such a case the bolt ends frequently strike on the cement before the strainer is clamped firmly .to the bowl. But with theflange extending internally, as shown, this cause of trouble is entirely eliminated. i

Also with the flange extending externally the water frequently leaks through the bolt openings of the flange, and passes downwardly through the roof and into the building; but by having the flange extending, inwardly any leakage through the bolt openings passes into the down spout without damage. Inasmuch as it is frequently desired to have the bolts loose so that they may be. readily removed, it is evident that elimination of external leakage through the bolt openings is of much consequence, as, with the loose bolts, the leakage would be considerable. With my arrangement of the flange these bolts may be as loose as desired; in

fact may be sufliciently loose to be removed flange extending around the edge of said strainer, and means for fastening said flanges together.

2. A drain-pipe connector, a strainer, and means for connecting said strainer to said connector, said means being positioned internally of said bowl.

, 3. A roof drain-pipe connector comprising a bowl, 3. flange extending internally around the upper edge of said bowl, e

strainer, 21 flange extending around the edge of said strainer, and bolts connecting said strainer flange to said bowl flange.

In testimony whereof, I hereunto set my hand.

GUSTAVE GARLSON.
